CHARLES C. NAEVE, OF PORTLAND, OREGON.

PoTATo-MASHER. I

y Specification-of Letters Patent.

Patented July 31, 1906.

Application filed May 23, 1905. Serial No. 261,801.

Be it known that I, CHARLES C. N AEvE, a citizen of the United States,and a resident of Portland, in the county of Multnomah and State ofOregon, have invented a new and Improved Potato-Masher, of which thefollowing is a ull, clear, and exact description.

My invention relates to apparatus for pulp- Its principal ob- ]ect is toprovide efficient meansfor successively reducing and beating the pulp.

Reference' is to'be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a broken central vertical longitudinal section lthrough oneembodiment of my invention. Fig. 2 is a transverse section therethroughon the line 2 2 of Fig. 1, and Fig. 3 is a horizontal .section taken inthe plane of the beating-shafts.

A designates a casing comprising a lower section 10, which may besupported at one end by legs 11 and at the opposite extremity by a clampadapted to engage the edge of a table and havin separated arms 12 12,

through one of W screw 13. Connected to this lower section by hinges 14is an upper section 15, which may be retained in its closed position bya catch 16. This casing furnishes a feedchamber B and a mixing-chamberC, the latter being enlarged or extended beyond the feed-chamber byparti-cylindrical portions c c, projectin ateach side thereof. In theend of the fee -chamber sections, adjacent to the mixing-chamber, is anannular recess to receive a perforated plate 17 ,in an axial opening inwhich and in a bore or boss 18, formed upon the outer head-of thefeed-chamber, is gournaled a shaft of a feed-screw 19. Upon the interiorof the feed-chamber, about the screw, are formed ribs 19, which lie atan angleto the thread' of the screw, they being shown as also at aslight angle to the a'xis of the cylinder. lThese resist the tendency ofthe material to travel circumferentially of `the chamber with the screw,causing it to advance more certainly and yet not offering any greatresistance to the rotation of the ',screw. At the inner end of the shaftof the feed-screw is a socket to receive the squared end 20 of an axialor central beater-shaft 21, which at its outer` end is journaled in anopenin through the mixing-chamber and has a ange 22 to retain it againstoutward ch operates a thumbmovement. It is provided with series ofoppositely-extending fingers 23 of such length that they approachclosely the upper and lower walls of this. chamber. Situated laterallyof the shaft 21 andextending axially of the side portions of themixing-chamber are beater-shafts 24 24, journaled at the outer end ofthe mixing-chamber in its head and projecting through the opposite headand being rotatablymounted therein and in lugs 25,

formed with the head of the feed-chamber.' These shafts 24 haveoppositely-projecting fingers 26, which are intercurrent with those ofthe shaft 21.

The screw-shaft extends outwardly through the boss 18 and has fixed uponit, by means lower'portion of the head of the mixing-cham# ber, 1s anopening leading to a` dschargechute 34. In the opposite or inner end ofthe mixing-chamber is an opening provided with a peripheral flange 35,which may engage a tubular projection 35a from a reservoir 36. In thetubular portion o the reservoir is shown a' valve 37 to control the flowtherefrom. j

The combination with a casing comprising a feed-chamber andan enlarged portion furnishing a mixing-chamber, of a screw situatedwithin the feed-chamber, an axial shaft provided with beaters rotatablein the mixingchamber, said screw and beater-shaft being connected toturn together, a lateral shaft provided with beaters extending throughthe mixing-chamber and outside th@ feed-chamber, and gearing connectingthe screw and lateral beater-shaft.

2. The combination with a casing comprising a feed-chamber and anenlarged portion furnishing a mixing-chamber, lof a screw situatedWithin the feed-chamber, an axial shaft provided with beaters rotatablein the mixing chamber, said screw and beater-shaft being connected toturn together, a lateral shaft provided with beaters extending throughthe mixing-chamber at each side of the axial shaft and outside thefeed-chamber, a gear rotatable with the screw, and a pinion fixed toeach of the lateral shafts and meshing with the gear.

3. The combination with a casing comprising `a feed-chamber and anenlarged portion forming a mixing-chamber, of ascrew rotatable Withinthe feed-chamber, a beaterin the mixing-chamber in alinement with thescrew, and intercurrent beaters arranged laterally with respect to thefirst beater.

In testimony whereof I have signedimy name to this specification in thepresence of two subscribing witnesses.
